L. CASPER. MACHINE FOR PASTING AND ATTAUHING LABELS APPLICATION FILED JAN.29. 1906.

, v LOUIS cssrssjosonroseo, ILLINOIS.

- MACHINE son Pss'rrirs Arm s'rmcnrne LABELS,

whom: it may Be .it known that I, Iiours'CAsrEa oi Chicdgo, in

the county of Cook and State of Illinois, have invented a new and useful and Improved Machine for Pasting fscription,"reference being had to'the accompanying drawings, forming a part of this specification, in which correspondingletters of reference in thediffer ent figures indicate like parts. I j p The object of my invention is toso construct a inachine-for andattaching labels to packages for I v shipment or. otherwise, that the label may be passed. automatically into contact with apaste supplying element whereby paste or other adhesive material pasted upon one side, may-be caused to adhere to the object to 'whichit is intended to be attached. I To these ends, my invention consists in the combi nation of elements hereinafter more particularly der f 0 scribed and definitely pointed out in the claims.

Figure 1, is a plan view of'a device embodying the featuresof my invention, Fig. 2,is a vertical sectional view taken upon the line 2, 1, viewed in the direction of the arrowthere shown, Fig. 3, is an en 'largedsectional view in detail taken upon the line 3-, Fig. 1, viewed in the direction .of the arrow there shown, Fig. 4, is a vertical sectional view taken upon the line 4-, Fig. 1, viewed as indicated by the arrow therein, and Fig. 5, is a front view of the paste-reserso voir. I

.Referring to the drawings, 1 indicates a cross-bar,

-to the ends of which is connected by means of screws 2, -2, parallel arms 3, 3, the whole forming a frame work-to which. is .rigidlyattached a re'arwardly :ex-.

5 "tended shank 'and handle 4. To the forward ends of .the arms 3 and extending between the two, is at tached a sheet-metal paste-reservoir 5, .within which is located 'a paste roller 6, having end journals 7, 7, which are fitted in suitable hearings in the ends of 46 them 3. The roller 6 projects above and slightly I in the rear of the paste receptacle, the rear wall 8 of and 5, having intumed flanges 10, 10, adapted to en- 5 gage corresponding grooves in the ends'of the paste receptacle, -is secured by means of said flangesand grooves to the top of said receptacle, said plate being free to slide back and forth in said grooves so that it may be adjusted with reference to the roller 6 to form a scraper for the purpose of regulating the amount of paste 'to'be delivered by the roller as hereinafter stated,

Arranged parallel with theroller 6 is a shaft 11 havingend hearings in the arms 3, 3, said shaft being preferably provided with collars 12, 12 to prevent endwise movement. Mounted upon the shaft 11, is one or more but preferably a plurality of wheels 13,

.the number of which mafy be varieu indefinitely c; I cording to .the size of the machine -and the character and width of the labels to be-used *therewith,f'said wheel or wheels being knurled upon-theperipheryF The journals ofthe shaft 11 are'mounted in elongated I I bearings 14, one of which is shown in Fig. 4-, so as to, permits. slight forward and backward play of said T shaft in the frame. Tapped into the cross-bar 1 in alin'ementwith the handle-4, is a. screw-threaded rod' 65 15, which rod extends forward in the plane of the shaft '11. Said rod is provided with .a bore 16, Fig. 3, into which is loosely inserteda' pin 17 having a head-thereon to which is attached a forkedbearing-piece 18, arranged to 'bear'against the shaft 11. 1 A coiled spring 19 isjmounted upon the part 15 and has one end arranged to bear against the head of said pin andth'e' other against an adjustingnut 20 upon the rod- 15 whereby the-tension of the'spring may be adjusted.

The pressure of saidspringserves to push the shaft.

forward so that the wheels.13 will be caused to press" against the'periphery of the roller G-With sufficient force toturn the latter when the machine is moved forward upon the wheels 13. This action causes theroller 6 to rotate in the direction of the .arrowand to convey the paste 21 upon its surfacetowards the wheels 13.

In ordento prevent a reverse action of'the paste roller so as to cause the paste to be piled up upon top of the plate 9, I attach'a ratchet-wheel22 to the shaft '85 11 which is engaged by means of a spring-actuated pawl 23 attached to the frame. A i

A smoothing roller 24 is journaled upon the horizon- V tal portion of a wire 25, Figs. 1, 2 and 4, the ends of which are bent upwardly and secured in vertical bores at the rear ends of the parts 3. v 4

A sheet-metal guard, generally designated by 26, is

' attached at its ends to the frame, said guard having a horizontal portion 27 and an inclined portion 28,-which latter extendsdownwardly into the bight between the roller 6 and the wheels 13. The object of this guard, which is also a guide, is to so direct the label 29 as it is fed between the paste roller and wheels, that the en-. tering wedge thereof shall not be directed into the paste box or against'the rear wall thereof.

The operation of said device is as'follows; The handle of the device being grasped by one hand, a label, with the printed side uppermost, is inserted beneath the guard with its lower edge in the bight between the paste roller and the wheels. The latter being pressed by the action of the spring 19 against the paste roller, causes the roller to rotate as the machine is pushed forward, with the wheels bearing upon the object to which the label is to be attached. This action serves to draw the label in between the wheels and paste roller, and toidirect it downwardly until the under face, upon which paste is evenly distributed by means of the 'paste ller, is brought into contact witlrthe package v,whe upon. the' wheels leave that part of directly upon and over the label. A continuation of with speed and certainty, and without danger of dis tributing paste in the wrong place.

- paste upon the roller may readily be determined.-

-as well as with the surface to which the label is to be the package upon which they are first pressed and roll the movement will cause the smoothing roller to press the entire surface of the label against the surface to which it is to be attached. As soon as the advance edge of the label is brought into contact with the surface to receive it or before the opposite edge shall have passed from the paste roll, the device should be tilted so as to'uit the wheels from the surface of the label and" cause all the pressure to bear upon the smoothing roll. Assoon as the upper end of the label leaves the paste roller the latter ceases to rotate provided'the device is tilted as sfatdl- This 'will prevent the wheels from rotatingwhile in direct contact with the paste roll, thus preventing them from receiving paste upon their peripheries, which might cause the outer'face of the next label to be slightly smeared with paste. A little practice will soon enable an operator to use the 'device- By adjusting the plate 9 the thickness o f't'he film of If long l'lfiI'lOWlBbCiBti-I'Qjgbiijifid it is obivo us that a single wheel insteadnfqfi-iill ll alliyzmflbejused; and, while I-prefer to make the"peiiphery'thereof'narrowasfililr'urri?its widtlmnayrabenvaried-=indeiinitely.-
